Abstract

reciclagem de lixiviado durante o processo de conversão lignocelulósica. a presente invenção proporciona um processo para a produção de açúcar fermentável ou um produto de fermentação a partir de uma matéria-prima lignocelulósica. o processo compreende a lixiviação da matéria-prima lignocelulósica com uma solução aquosa para remover, pelo menos, os sais de potássio a partir da matéria-prima lignocelulósica sem significantemente hidrolisar a hemicelulose e a celulose, produzindo assim uma matéria-prima lixiviada e lixiviados. o lixiviado é removido da matéria-prima lixiviada e é concentrado. a matéria-prima lixiviada é hidrolisada para produzir o açúcar fermentável, que pode ser fermentado para produzir um caldo de fermentação que compreende o produto de fermentação. o lixiviado concentrado é recirculado para uma ou mais etapas do processo que envolve a adição de álcali para ajustar o ph uma corrente de processo.leachate recycling during the lignocellulosic conversion process. The present invention provides a process for producing fermentable sugar or a fermentation product from a lignocellulosic feedstock. The process comprises leaching the lignocellulosic feedstock with an aqueous solution to remove at least potassium salts from the lignocellulosic feedstock without significantly hydrolyzing hemicellulose and cellulose, thereby producing a leached and leached feedstock. leachate is removed from the leachate and concentrated. The leached raw material is hydrolyzed to produce fermentable sugar, which can be fermented to produce a fermentation broth comprising the fermentation product. The concentrated leachate is recirculated to one or more process steps involving the addition of alkali to adjust the pH of a process stream.
